In front of Jason, the book given by the old knight had these clear words written on it—
"Every secret technique has its own characteristics!"
"Different secret techniques can complement each other or may even conflict!"
"But there is one exception to this rule!"
"It does not conflict with any other secret techniques, nor does it provide any assistance."
"That is: the Flash Technique!"
"The initial Flash Technique appeared in the Duyi School of learning, where it was used as a sort of entrance test; later, in the Dur School, it was developed and elevated to a secret technique that could assist in attacks."
"Of course, most of the time, it's just used for illumination."
...
Jason had the Flash Technique!
After discovering that secret techniques could complement and conflict with each other, he had temporarily given up on studying them.
Now, there were no such concerns.
At the same time, there were no concerns about "Charge" and "Whirlwind Dance" either.
